Xpoz Social Search

Security checks for vulnerabilities and agentic risk

Overview

This skill is a disclosed social-media search integration, with the main caveat that it relies on external setup and an unpinned npm tool.

Before installing, confirm you trust Xpoz, the mcporter npm package, and the xpoz-setup skill. During setup, check that OAuth and MCP configuration point to the expected Xpoz service and avoid granting access if the flow requests unexpected permissions.

Insecure DependenciesIntroduces malicious components through unsafe dependency sources
Skill Instruction HijackingAlters the agent's session goals or safety constraints when the skill loads
Agent Memory PoisoningWrites attacker-controlled rules into memory that affect later sessions
Remote Payload Retrieval and ExecutionFetches external code whose behavior can change after review
Embedded Malicious CodeShips malicious scripts inside the skill and executes them locally

Low

Category: Not specified by scanner
Confidence: 87% confidence
Finding: The manifest description advertises broad capabilities like 'Search Twitter, Instagram, and Reddit posts in real time' and 'Social listening, brand monitoring, and competitor research made easy for AI agents' without specifying how or when the skill should be invoked. In a manifest file, this kind of open-ended capability wording can overlap with many generic research requests and lacks negative examples or scope boundaries.
